IMPRQVEMENT IN HARVESTER-BINDERS.

The Schedule referred to in th/aleletters Patent and making part of the same.

To all whom Jif 'ma/y concern Beit known that I, J osera BARTA, of La, Crosse,

i-n the county of La Grosse and State ofWiseonsiu,

have invented a new and useful Improvement in Bindv ing Attachment for Harvesters; and I do hereby de: clare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being' had to the accompanying drawing forming part of this specification, in which- Figure 1, Sheet I, is a top view of a harvester-platform to which my improvements have been attached.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish animproved rakiug-and-binding attachment for harvesters, which shall be so constructed as to take the out grain as it falls upon the platform, push it back, gatherf it into4 gavels, bind it securely, and push the bound sheaf from the machine, and which shall be effective and reliable in operation; and

It consists in the. construction and combination of the various parts of the apparatus, as hereinafter more fullydescribed.

A is the' platform of the machine, upon which the grain falls when out.

` B is'the reel, which revolves in .bearings in the framework-of the harvester, and which is driven from the harvestec by.Y achan,l in the ordinary manner.

-- C is a rake attaehedto the outer ends of two arms D, the other ends of which are pivoted to two ,of the reelarms near their outer ends.

To one ofthe arms D,near its outer or pivoted end,

is pivoted one end of a connecting-rod, E, the other, end of which is pivoted to the rear end of an arm, F', the forward end o'f 'which is pivoted to one ofthe reelarms; and to anarm riding upon the reel-shaft.

To the arm F is pivoted a friction-roller or wheel,

to the reel-posaand through the center of which the reel-shaftpasses.

The rear part h of the outer wall of the groove or channel ofthe plate H 'is movable, `and is pivoted at itsl upper end to the-said plate H.

The lower end of the movable piece h1 is pivoted to the rear end of a catch-bar, I, the forward end of which 'passes through a guide or keeper, h, attached to the plate H.

The lower edgeof the bar I is notched to catch upon a catch formed in or attached to the keeper, h.

The bar I isfheld down upon the catch by aspning,

I J, attached to the plate H, and which' presses .down

upon the upper edge of the bar I.

by and with the reel B in-its revolution.

As the rake O strikes the platform Ait moves back along-.said platform, pushing the cn't grain back into position to be taken by the gathering-rake and gathered into gavels.

As the pulley' rake O is raised in nearly a perpendicular direction, and is then carried -around with the reel B.

by means of the catch-bar I the distance that the rake O moves back along the platform may be regulated according to the length of the stalks of the grain being cut.

K is a bar or plate that' supports the ends of the cut grain while the gavel is being gathered, to prevent the grain being cut from mingling with the grain being gathered into a gavel.

The bar or plate K rod, L, and is held in an inclined position when lowend of which is attached to the outer end of the lower attached tothe 4fralne of' the machine or to an arm pivoted to said frame.

and again raised .to .allow the grain Ato drop to the platform A, by raising and lowering the said rod L.

The outer end of the rod L is bent upward and forward, and its en'd isfpivoted to the frame of themachiue a littlebelow and in frontof the reel-shaftw The'other or inner end of the rod'Lv is attached to the rear end of au arm 'or lever, N, the forward end of which is pivoted to the frame of the machine a little below and in front of the reel-shaft.

O is a rope or chain, one end of which is attached to the arm or lever N. The chain or rope O passes over a guide-pulley?,

` G, which works inaca'm-groove in a plate, H, attached By this construction the rake O is carried around- G strikeslthe .movable piece hl the By adjusting the position of the movable piece hl is hung from and pivoted t a' ered to receive theI grain by a cord or chain, M, one

edgeof the said bar or plateK, and'its other end is The bar or plate K is lowered to receive lthe grain,

pivoted to the frame-work of the machine at a highery elevation than the arm or lever N, and its other end is attached to the upper end of a lever, Q, the lower end of which is'pivoted to a support attached to the lower part of the frame of the machine.

The lever Q is operated to raise -the bar or plate K and its attachments by a projection of the cam R, attached to the shaft S, which'revolves -in bearings attached to'the frame-work of the machine, and isconnected with the driving mechanism of the harvester by suitable gearing, so as to be driven by said driving mechanism.

To the rear end of the shaft .S is attached, 'or .up'on it is formed, a crank, T, to the crank-pin of which is pivoted the lower end of the connecting-rod U, the

upper end'of which is pivoted to the short arm of the elbow-lever V, which is pivoted at its angle to the upper end of a post attached to the frame' of the inachine.

To the lower end of the long arm of the lever V is pivoted the inner end of the handle W ofthe gathering-rake X, so that the said rake X may be moved back and forth across the platform A to gather the ont grain pushed back by the reel-rake O into agavel.

The rake X is connected with the rod L, which. serves as a guide to said rake in its forward movement, aud supports it away from the platform in its outward movement, so that the said rake in its outward movement will not come in contact with the grain upon the platform.

' The rake X descends to-the'platform A, just in therear ofthe shoulder formed by the recess made in the outer end of the platform, to receive the caster-wheel, so that the said rake may pass down freely outside of the grain.

l f al is a cleat, attached to the platform A beneath theV ,rake X, to support the middle parts ofthe grain while being gathered into a gavel, to prevent the stalks of grain from getting beneath the rake-teeth while being gathered.

a2 is an incline, up which the gavel is swept by the rake X to be bound.

Y represents the spool, upon which the bindingcord is wound, which is pivoted to the frame-work of the machine in such a position as to bc out of ,the way, and which is lprovided with a lrubber washer at ,one end, to prevent the cord from unwinding by the jar of thc machine.

From the spool Y the cord passes through the guide-eyes Z, which are provided witha spring to give the necessary tension to the cord.

From the guide-eyes Z the cord passes along a groove in the convex edge of thel curved finger A1, and through an eye in the end of said finger.

As the machine is started the finger Al is moved l downward and` passes through a slot in the forward end'of the top plate B of the device for forming the knot, where the end of the cord is grasped and held by a pair of jaws. l

The linger *A* is then withdrawmbringing the various parts of the bindingl device into the position shown in g. 2, ready to receive'the gavel.

upper end is, attached to the end of-a rubber strap,

'The rubber strap F passes over a guide-pulley, G1, attached to the upper partv of the frame-work of the machine, audits other end lis attached to a projecting arm formed upon the outer or, concave side of the uger Dl.

The elasticity ofthe rubber strap F1 allows the cord C1 to adjust itself to and rmly hold different-sized bundles. v

.As the entering gavel forces hack the ybinding-cord and the holding-cord (ll the nger Al again descends, drawing the binding-cord about the bundle, and carrying it into the knot-tying device, where the 'knot is tied andthe cord cut oli, its end being again grasped and held ready for the next bundle.

While the knot'is being tied the tingerDl is withdrawn and the finger H1, formed by extending the finger Dl in the other direction, descends, and, as the cord-is cut after the knot is tied, pushes the bundlet from the machine.

The linger A? is pivoted to a short shaft, I, and to it is pivoted one end of a connecting-bar, J l, the other of which is pivotedto theupper end of the bar or lever X1, the lower end of which is pivoted to the framework of the machine. The lever K1 is operated to'raise the nger A1 at the proper time by a pin or projection, L1, attached to the side of thev cam Ml, attached to the shaft S, and which acts upon the` rear end of the finger A1 -to force it down at the proper'time.

Y Upon the lower end of the connection-bar Jl is formed, or to it is attached, a projection or pin, N11' which strikes against the lower edge of the finger H1 as the finger Al is being raised, and raises the finger H, lowering, at the same time, the-finger Dl into position to receive and hold the bundle.

The finger )l is locked and held against the .pressure of the gavel by the lock-bar O2, which is held down by a spring, P1, and takes hold of a pin or projection, Q, attached to the pivoting-armof the fingers DH.

As the shaft S revolves the cam R' raises the bar 0l and unlocks the ngers Dx H1, and thecam Ml 'raises the linger Dl to release the bundle, and lowers the nger Hl to push it from its place.

As the finger A1' passes through the slot in the plate Bl it passes close below the clamp T', and presses the end of the binding-cord between the jaws of said clamp, where it is held.

As the finger AI again enters the knot-tying apparatus after a gavel has been received it again'passes i beneath the clamp T', and presses the cord between the jaws of the said clamp and remains stationary- While the knot is heilig tied, both ends of the cord being now drawn over the twister U'.

Motion is communicated to the' knot-tying apparatus from the plate V'. jf'

A s the plate V moves forward the two ends of the cord are grasped between the jaws of the iovable clamp W', one of which jaw's is formed up!V of the plate X', pivoted to the plate V; ant` jaw is pivoted to said jaw and is'held fc. spring, Y. v

The movements of the plate X are limitfa" trolled bystops attached to vthe plate B1.

As the movable clamp W moves forward the two cords into the lips of the twister ne revolution of which a loop is formed upon the said cord.

The twister U' works in bearings. attached to the plate B2 and upon its rear end is formed a small gearwheel, Z', the teeth of which mesh into the teeth of the rack-bar A, which extends back along the under side ofthe plate V', and is vpivoted to the end of the vbar B?, placedl above the plate V', said pivoting-pin passing through a V-shaped slot in the plate Theother end of the bar Bz is pivoted tothe plate B, as shown in fig. 7.

While the loop is being formed the cord is cut be-v tween the movable clamp W' and the holding-clamps T by the cutting-blade O?, which is pivoted to an arm of the plate X', as shown in g. 8; to which arm is riveted a thin plate, D, which prevents the loop from slipping from the twister V' too soon, and which also prevents the cord from slipping through the hook while the knot is being drawn tight.

As the movable clamp W moves forward it carries the ends of the cord within reach ofthe curved hook E2, Vwhich is projected through the -twister U', and consequently through the loop of the cord, and by whichthe ends of the cord are drawn through the loop, forming the knot.

The hook E is formed upon or attached to the plate V', so as to be operated by the movement lof said plate V'.

As the ends of the cord are drawn through the loop they enter aslit in a beveled plate, E, against 'which the knot is drawn tight, thus preventing the loop from following the hook E2. Y The armed plate X', with which the movable clamp W' is connect-ed, is operated by a cam, G2, attached to the plate V and by stops attachedto the plate B1.

'The knife()2 is moved forward at the proper time by stops attached to the plate B1, and with which the movementof the plate X'brings it in contact.

' The movable jaw of the holding-clamp T' is released to allow the end of the cord to be drawn out by the movement` of the movable clamp W by the cam Hi'attached to the plate V', and which moves along the arm ll2 formed upon or attached ,to the said movable jaw of the holding-clamp, and pushes back the lock-bar or button J 2, which is moved back by the cam'H2, and is moved forward to again lockthe bar by the advance of the pivoted bar B2.

The cam El2 rests against the arm lz and holds the jaw of the clamp steadily as it moves back to push back the lock-bar Jz and as it moves forward, the. said jaw being only released for a singlev instant after the cam H2 has moved away from the arm I2 and before the bar B2 has pushed the lock-bar J2 forward; but during this instant thel end of the cord `is drawn from the holding-clampI 'l" by the movement of the movable clamp W.

. All the movements of the knot-tying device are produced by a` slight forward-and-backward movement' of the plate V.

To the plate V is attached a pin, K2, which enters, a .slot in the end ofthe lever L?, which enters beneath the plate B1, and is pivoted to the frame of the machine, as shown in figs. 3 and 5.

To the other end ofthe lever Lz is pivoted one end 'of the connecting-bar M2, the other end of which is pivoted to the lower end of the level' N.

The lever N2 is pivoted to the frame-work of the machine and its upper end is made somewhat in the form cf a shoe, as shown in g. 3, so as to b e moved' in both directions by the cam R attached to the shaft S, as shown in 'g. 3.

The hole in the plate Bl through which the finger A passes is covered by a small cap-plate, O2, pivoted to said plate,B, held forward to close said hole by the rubber spring P2, and pushed back by the entering-finger Al. e

In the said hole is also secured a small rubber plate, Q, through which the entering-finger A1 passes, and which, in connection with the cap, is designed to prevent the entrance of straws, dirt, 85e.
